Fisher 67CFR-239 direct-operated regulators and filter regulators
are typically used to provide constantly controlled, reduced
pressures to pneumatic and electropneumatic controllers and other
instruments. These are suitable for most air or gas applications.
Other applications include providing reduced pressures to air
chucks, air jets, and spray guns.
Principle of Operation
Downstream pressure is registered internally on the lower side of
the diaphragm. When the downstream
pressure is at or above the set pressure, the valve plug is held
against the orifi ce and there is no fl ow through the regulator.
When demand increases, downstream pressure drops slightly allowing
the spring to extend,
moving the stem down and the valve plug away from the orifice. This
allows fl ow through the regulator.
